Pinout Diagram for 2010 JBL underseat Amp

Anybody happen to have the pinout diagram for the underseat amp on these? Toyota made it hard on these as all of the wires in the door are just white. So no tracing a wire visually like i usually do on all of my toyotas with amps underneath the seat or console. I did find some but they are in like 144p i guess the original photos may have gotten deleted over the years. But typically someone on here will always know the answer so I have asked.
Setup wise, the stock jbl system sounds great. Volume is plenty. But I swapped to coaxial speakers in the door for improved sound (I couldn't hear the tweeters on the dash very well). Now it sounds like its more centered around me as a driver, but I just lost a lot of bass from that. Sensitivity wise they are equal though. If I can find the pinout on the amp i should be able to send a signal wire to the back and wire in a small amp in sub in like an hour to fill the bass i need.

 

Can someone move this to audio and electronics? Thought i was in there...
